My invention relates to paper machinery, having particular`V relation tothose parts .which are directly associated with thewire..`

vof Fig. 1,;

One object of myinvention is to provide a Fourdrnier-part comprisinginde lendently removable ,table-roll and suctionox sections. Suchconstruction permits the re-v lacement of the wire in one-third the'time eretofore considered, practical and' with,` f a correspondingdecrease `1n maintenance charges. It also makes possible the removal ofthe structure by hand, thereby eliminat-` ing the necessity for theexpensive poweractuating mechanism embodiedAAV in theprior 1.5 artmachines.

Another object of my invention to provide apparatus of the classdescribed, wherein; the removable Fourdrinier part may be lowered froman upper workingpositiomto a lower position in engagement Withmean'sadapted to facilitate the removal of .said part. l.

A further object of my invention is to 'provide ower means for raisingand. lowering. part between the working., .and removing positions, thepower means also the ourdrinier serving to .operate the couch roll'longitudinal-ly of the Fourdrinier part, so tha `wiremay -be draped inlaceto give ample clearance for inserting t e removable parts,

without injury'to the wire'. v l i A'still further object of myinvention is `to provide a'Fou'rdrinierpart comprising hinged sectionsadapted to cooperate with a wire, and power means whereby the'pitch ofsaid wire may be adjusted at an intermediate point. v Y' A still.further object of my invention is to provide a bodily movableFourdri-nierpart characterized by maximum vibration at the v breast rollend thereof.

Withthese and other objects and applications-I in mind, my inventionfurther con-v sists in the details of construction and operation andarrangement, -hereinafter described 4 and claimed and illustrated in theaccompanying drawing, wherein Fig. 1 is a side elevational view of apaper making machine embodying my invention;

Fig. `11 is a to plan view of one of the gearboxes kwith t ecover-removed.

Referring to the drawing, the paper-making machine thereindisclosedcomprises broadly a head-box 1 having` a so called.

voith inlet 2 positioned to discharge onto a breast-roll and?) of awire' 4 supported by a removable Fourdrinier part 5, -vthe pul being'finally transferred -from a couch-rol end'6 of they wire 4 to the usualdrying rolls `(not shown).

-Th'e Fourdrinier part 5which embodies the principal features vof myinvention, com-A rises a removable table-roll section 7, andindependently removable contiguous suctionbox section 8, anda suction orcoueh'roll 9 bodily movable onjways 11 extending'longitudinallyof thewire 4. n

Considering the table-roll section 7 in greater detail, a pair oflongitudinally extendingside table-rails` 12 and 13 are providedwithbearings 14 for the support o the usual table rolls 15. The rolls 15togetherconstitute an upper workingsurfacepl providing a support for theFourdrinier wire 4. According to my invention,a rear or couchlioll end17 of the rails 12 and 13has pivotal -mountings 18 .and 19 which arerespectively supported on adjacent rear ends 21 of side portions 22 andl23 of a supporting frame 24.

Each of the mountings or'bearings 18,19

comprises a vertical trunnion pin 25 which extends upwardly through theadjacenttable rail from a horizontal bearing surface 26.

The rail-supporting surface 26 is formed on an upper side 27 of alongitudinally extending member constituting one of the side frameportions 22, 23. The vertical trunnion pin 25 and the bearing surface 26thus permit a limited horizontal vibratory movement of the table rails12, 13, and rolls 15,-this movement being substantially negligible atthe couch-roll end 17, but a maximum at the breast roll end 3 of theFourdrinier wire.

The side portion 22 of the supporting frame 24fcomprises rear and frontbox-like end sections 28 and 29 respectively, upper sides 31 of whichare interconnected by an angle 32 posltioned directly beneath but inspaced relation to the adjacent table or shake rail 12. The angle 32 atspaced points intermediate the ends/thereof is provided with downwardlyextending angle sections 33 and 34 which are secured to a reinforcingangle 35 having a horizontal section 36 positioned intermed1ate thedepending sections 33`and 34 and end sections 37 and 38' respectivelyextending upwardly to the adjacent sides of the box-like sections 29 and28. The opposite side portion 23 embodies similar horizontal andvertical reinforcing angles 39 and 41 and enlarged rear and front endsections 42 and 43. The rear box sections 28 and 42 are interconnectedby an angle 44, while the front box sections 29 and 43 areinterconnected by an angle 45.

The lower ends of the vertical angles 33, 41 and 34 may be connected bytransverse angles 46 and 47 respectively.

The table rails 12 and 13 are interconnected adjacent to the verticallangles 34 and 41 bya shaft 48, each end of which is provided with a in49 which extends upwardly through the adjacent rail and terminates in asupporting head 51 in the form of a supporting bolt head or nut, asimilarly supported shaft 50 extends between the vertical angles 33 and41.

As shown in Fig. 8 the portion of the rails 12 and 13 respectivelyadjacent to the vertical angles 34 and 41 may be supportedby a pair ofresilient devices 52 permitting lateral vibratory movement about thepivotal mountings 18 and 19. Each of the devices 52 comprises a pair ofspring strips 53, the upper ends of which are bolted to flanges 54extending from opposite sides of the shaft 48. The lower ends of thestrips 53 `are mounted on flange 55 extending from opposite sides of thetransverse angle 47. The portions of the shake rails 12 and 13 adjacentto the vertical angles v33 and 41 respectively are similarly supportedfor lateral vibration by means of resilient devices 56, 56.

The table rails`12 and 13 may be further supported adjacent to thebreast roll end 3 of the wire 4 to afford the desired lateral vibratorymovement by means of a pair of pedestals 57 and 58, respectively. Thesepedestals extend upwardly from a supporting floor surface 59 to bearings61 and 62 respectively secured to adjacent flanged ends 63 of the shakerails 12 and 13. The bearings 61 and 62 serve to support shaft 64carrying a breast roll 65 around which the wire extends.

As illustrated in Fig. 9 each of the pedestals 57, 58, comprises a base66, a block 67 which is removable secured thereto by bolts 68, and aspring structure 69. `The structure 69 includes a pair of spaced strips71, the lower ends of which are secured to opposite sides of al bracketmember 72 secured by bolts 73 to the removable block 67. The upp'er endsof the spring strips 71 are spaced by a member 74 pivotally mountedthereon by pins 75. The member 74 is provided witha central recess forthe reception of a tongue 76 extending downwardly These parts may bepivotally connected together y a pin 75. Such mounting` permits thebreast roll and connected shake rails 12- and 13 to move in a verticalplane about the spring structure 69 without interfering with theV.lateral vibratory movement thereof. It will be noted that thepedestals 57, 58 serve to support the breast roll 65 and adjacent endsof the shake rails 12 and 13 independently of the main supporting frame24, the latter in turn supporting the intermediate resilient devices 52and 56, 56 aswell as the vertical pivotal mountings 18 and 19 at thecouch-roll end 17.

My invention also contemplates the hingin of the frame 24,-whereby thecouch-roll end 17 may be moved vertically to adjust the pitch of thewire 4. To`this end, a pair of supporting pedestals 78 and 79 arepositioned directly below the front box sections 29 and 43. Eachp'edestals 78, 79 comprise a bracket 81 extending upwardly from the base66 and a removable bearing block 82 embodying the lower half 83 of apivotal bearing. 84, an upper half 85 of which is formed on a bracket 86secured to an underside 87 of the box section 29, 43. T heslearing parts83 and 85 embrace a pivot pin Such vertical adjustment of the frame 24about the pivotal bearings 84, 84 as may be necessary to establish-thedesired pitch of the wire 4 may be effected at the couch-roll end 17 bypower means 89. The power means 89 comprise a ,pair of spaced screw-]ack devices 91 and 92 positioned directly beneath the rear box sectlons28 and 42, respectively, on thefloor surface 59. The devlces 91 and 92are interconnected by a com- Imon cross shaft93 extending to a gear box94 having a control element 95. The ear box 94 is connected to a mainoperating s aft 96' extending longitudinally of the Fourdrlnier part 5.The main power shaft 93 is driven by a motor 97. As shown, the gear box94 is so constructed that when the control element 95 is in one 93 isconnected to the main-power shaft-96 to operate the screw jacks 91 and92 in one direction. When the contact element-95 is from the adjacentbearing.v

position, the cross shaft v movedinto 4another position, the screwjacksA l 91 and 92 are operated in the reverse direction ofv movementinto an intermediate poprises a post 98, a lower end of which carriesV awheel 99 which meshes with a worm '101 on the cross shaft 93. The post98 may be guided'by means of acasing 102 tor movement into and out ofengagement with a spherical recess 103 formed in thelowerend of ablock104 mounted ontheunderside of the rear box y sections 28 42. The upperend of the post 98 is Jformed wit-ha surfacev complementary to that ofthe Arecess 103. When it is desired to 'adjust the pitch of the tablerails 12 and 13,' the control element 95 is moved into the positioncausing'the desired vertical movement of the post 98and hence the frame24 about the pivotal mountings 84.

My invention still further contemplates the lowering of the table-rollsectionf7 from the-upper working position of Fig. 1 to the lowerposition of F ig. 2' wherein the frame 24 and associatedv parts mayberemoved from the machine to permit the replacement of a damaged orWorn out wire. Accordingly, I provide power means 1-05 at the hingedfront end of the frame 24, said power means constituting supportsauxiliary to the bearings 84, 84, permitting the removal of the blocks67 andy82 and, thereafter, in combination, with the power meansl 89, thelowering of the structure 24` into the desired position, as

will presently appear.A -The power means 105' comprises a pair ofscrew-j ack devices 106 and 107 corresponding to the devices 91 and 92,.Each of the devices' 106, 107 includes a vertically movable ost 108, theupper end of which is movab e into engagement with the' bearing bracket86, while a lower end is provided with a wheel 109 in mesh' with a worm11.1 on a cross shaft 112. The shaft 112 is connected to a gearbox 113corresponding to the gear box 94. The gear box 113. is provided with acontrol element 114 having raising, lowering and neutral positions, asin the cas/e of the control elements 95.

The rposts 1-08 may be inclosed in a housing 115 which forms a part ofthepedes` tals 78 and 79. 1 The housings 115 are provided witlralignedrecesses 116 for the reception of removable Lbeam rails 117 that extendtransversely of the machine into the side aisle. The casing 102 for thescrew-jack devices 91 and 92 is also provided with aligned recesses 118for the reception of removable rails 119 extending into the side aisleof the machine. The movement of the :trame 24 over these rails may befacilitated by wheels121, ofwhich four are shown, two being`respectively mounted on the side frame portions`v22 and y23 adjacent tothe breast roll 65 and the remaining two being 'similarly mounted at therear end of the The further vertical movement of the po'sts 108 causeadjustable frame abutments to en' gagethe flanged ends 63 of the shakerails 12 and 13, respectively, causing the load carried by thebreast-roll pedestals 57 and 58 to betransferred to the posts 108. Thefront and rear posts 108 and 98 now support the frame 24,:thebreast-rol1 65, table rolls 15 andv rails 12 and 13, permitting theblocks 67 and 82 to be removed.

The. control elements 95 and 114 are now moved in-to their loweringposition, with the result that the posts 108 and 109 move downwardly,dropping the table section 7 from its upper working position to itslower position wherein the wheels'121 engage the rails 117 and 1118.Thetable section 7 may .now be moved laterally of the machine'into theside aisle. Such movement occurs independently of the suction-boxsection 8.; I

The suction-box section 8 has a rear end 125 thereof pivotally mountedon bearings 126 provided Y by-fspaced pedestals 127 respectively,positioned at the opposite sides of the section.v Each of the pedestals127 includes a removable bearing block 128 corresponding to theremovable blocks 82 associated with the pedestals78 and 79 in the tablesection 7. A front end 129 .of the suction-box section 8, which isadjacent to the rear end 17 of the table 'rails 12 and 13, is supported`on power means 131 comprising screw-jack devices 132identical withthose for the table-section 7. The devices 132 are intereonnectedbyacommon shaft 133 leadjing to a gear box 134 having an operating element135 for controlling the connection between the shaft 133 and themain-operating shaft 92.

Should it be desirable to change the pitch of the wire 4 independentlyof or in conjunction with the table section 7, the control element 13.5is operated'into its raising position, wherein `the main shaft 96 isconnected to cause the devices 132 to move vertically the front end 129of the suction-box- 8.v Such movement occurs about the pivotal bearings126. Additional power means 136 corresponding to the table power means105 may be provided adjacent to the pedestals 127, and it comprises apair ot' screw-jack devices 137 having an inter-connected power shaft138 extending to a gear box 139 controlled by an element 141.

The front and rear screw-jack devices 13 and 137 have recesses 142 intheir casings for the removable reception of front and rear rails 143and 144 adapted to co-operate with wheels 145 carried by the suction-boxsection 8. IVhen it is desired to remove the section 8, the controlelement 141 is moved into its raising position, causing the rearscrew-jack devices 137 to lift the suctionbox end 125 from the bearingpedestals '127, whereupon the blocks 128 may be removed. The controlelements 135 and 141 are then actuatedinto their lowering position,permitting the screw-jack devices 132 Aand 137 to lower the suction-bexsection 8 from its upper working position to a lower position whereinthe wheels 145 engage the rails 143 and 144. The suction-box section 8may now be removed from the machine into the side aisle.v

A still further feature of my invention is the provision of means,whereby the suction roll 9 may be movedupon power backward from therunning position to give slack to the wire 4. As shown in Figs. 1, 2 and3, such construction involves the mounting of the oppositeends of acouch-roll shaft 146 on bearing pedestals 147 and 148 which arerespectively supported on the ways 11 extending longitudinally of themachine. Each of the ways 11 is providedwith a central recess for ascrew shaft 149, one end of which extends into a threaded portion of thepedestals 147, 148. An opposite end of the screw shaft 149 is geared toa transversely extendingr shaft 151 which terminates in a gear box 152having'a control element 153. The gear box 152 is connected to -t-hemain operating shaft 96, as in -the preceding gear boxes, and it is A ofsimilar design. I When the element 153 is actuated into one position,the pedestals 147 and couch-roll 9 are actuated to slacken the wire 4,but when said element is oppositely actuated, the couch roll 9 is movedto tighten the wire 4. l 1

Assumingl the table-roll section 7 and the suction-box section 8 inltheir laterally removed positions in the machine aisle and the suctionroll 9 moved backafording a maximum slack in the wire 4, the Fourdrinierpart is in the position permitting the removal and replacement of thewire 4. When a new wire 4 is positioned in the machine, the table-rolland suction-box sections 7 and 8 aremoved on their supporting rails intocorrespondingly A is then reversely operated to cause the front posts108 to move downwardly, permitting the load of the breast-roll andadjacent table-rolls 12 and 13 to be transferred to the pedestals 57,58, and the lead of the front end of the frame 24 to be assumed by thebearing pedestals 78, 79. The suction box section 8 is similarlyreturned toits original position shown in Fig. 1, and the suction roll 9is then moved forward by the power shaft 96 through the gear box 152 torunning position. The pitch of the wire 4 is next adjusted by the posts98 or 131 or both.

lVhile I have shown only one form of embodiment of my invention, for thepurpose of describing the same and illustrating its principles ofconstruction and of operation, it is apparent that various changes andmodifications may be made therein without departing from the spirit ofmy invention, and I desire, therefore, that only such limitations shallbe imposed thereon as are indicated in the appended claims or demandedby the prior art.
